GBAUMAN, .OF SEATTLE, WASHINGTCSN SEDIMENT COLLECTING STOPIPERApplication filed June 19,

Our invention relates to the art of bottle stoppers and mostparticularly to that type that is adapted as stoppers for beverages andsimilar liquids which when allowed to stand precipitate the solids inthe form of sediment.

Most beverages of the type that will produce a sediment have stored upwithin them gases of considerable pressure which, when the bottle isopened, effervesce and cause a violent mixing. If, when this takes placethere is any appreciable amount of sediment it is very thoroughly mixedwith the otherwise clear liquid. Therefore i It is a primary object ofour invention to provide a bottle stopper that will collect the sedimentas it is precipitated and permit its easy removal from the bottle.

Another object of our invention is to provide a sediment collectingdevise that may be inserted in the neck of a bottle and be held in placeby a conventional crimped cap.

A further object of our invention is to provide a sediment collectingdevise that will trap and retain the sediment so collected.

In general the object of our invention is to overcome the variousdifficulties set forth above and provide a bottle stopper which ischaracterized by its efliciency and its simplicity.

The abovegeneral objects of our invention together with others inherentin the same are obtained by the devise illustrated in the followingdrawing, the same being preferred ex- 1 emplary forms or modificationsof our invention, throughout which drawing like refer ence numeralsindicate like parts.

Figure 1 is a cross sectional view through our invention showing thesame secured to an inverted bottle by a conventional type of wire clamp.

Figure 2 is a cross sectional view of a slightly different form of ourinvention, the same being shown as secured to an inverted bottle bymeans of a screw thread.

Referring to the drawing, numeral 5 represents a hollow cap or stopperwith the cavity 6. This stopper may be made of any suitable materialsuch as glass, pottery, bakelite, treated wood or the like.

A gasket 8 of some soft material is used to 1928. Serial no; 236,525.

form a seal between the stopper and the top ofbottle 10. The method ofsecuring the stopper to the bottle will depend in a' large measure uponthe liquids it is desired to bottle. V

In Figure 1 we have shown a conventional type of securing means whichproduces its securing pressure by means of the member 12. Revolvingabout a pivot 13 until the pivot 14 has passed beyondthe line joiningthe piv- 0t 13 and groove 16 in cap5. The toggle action'so obtainedexertsconsiderable pressure and provides a lock that tightens whenpressure is applied to the fluid.

In Figure 2 we have shown the cap 5 secured to the bottle 10 by means ofthe threads 18. Further, inasmuch as this type of stopper can not be asquickly removed as that shown in Figure 1, we provide as part of cap 5 acircular shelf 19 having a flat lower surface 21 and a sloping uppersurface 22.

M ethod of operation To take advantage of the sediment collectingproperties of our stopper it is necessary to invert the bottles and letthem stand on the stoppers until it is desired to use the liquid thusstored. In the form shown in Figure 1 it will be clear that the sedimentmay drop unhindered into the cavity 6 and when it is. so desired to openthe bottle it should be brought to a horizontal position. The lock lever12 is moved to the unlocked position and the cap removed and the bottlequickly restored to a vertical position. Sediment will often solidifyand then the bottle may be inverted.

I Inthe type shown in Figure 2 the sediment in settling passes over thesloping surface 22 into the chamber 6. When it is desired to open thistype the bottle must be inclined sufficiently from its upright positionso that the fiat side 21 will prevent the sediment from flowing backinto the bottle 10.

Other details of operation and construction of our invention would be soobvious to those skilled in the art that we believe that no furtherdescription is necessary. Manifestly, changes may be made in the form,proportion, and arrangements of parts of our invention Without departingfrom the spirit thereof:

That we claim is 1. A bottle stopper adapted to be secured to the mouthof a bottle, a cylindrical sediment collecting cavity disposed Whollywithout and co-axially with the bottle, a circular shelf formed as partof the stopper, disposed between the bottle engaging portion of thestopper and the said cavity adapted to retard the sediment returning tothe bottle when the bottle is held in a slanting position.

2. A bottle stopper, of the class described comprising a cap-like deviceadapted to be securely fastened onto the mouth of the bottle; acylindrical sediment collecting cavity within said device, said cavitybeing disposed wholly Without and Clo-axially with the bottle and anannular shelf disposed between the bottle and the said cavity having asloping surface facing the bottle engaging portion of the stopper and aflat surface, nor1nal to the axis of the cavity, facing said cavity.

In witness whereof, we hereunto subscribe our names this 11th day ofJune A. D. 1928.
